The NI-9485 is a digital I/O module categorized under C Series Digital I/O. This module is designed to facilitate robust and efficient interfacing with external devices through its 8 SSR Solid State Relay Output Channels. Each channel is capable of switching up to 60 VDC or 30 Vrms, with a maximum switching current of 1.2 A per channel for up to 4 channels and 750 mA for all 8 channels.
One of the key features of the NI-9485 is its channel-to-channel isolation, which enhances system reliability and protection. The module boasts a swift relay open time of 0.5 ms and a relay close time of 9.0 ms. While in active mode, the resistance is a minimal 200 mΩ, and the off-stage leakage is just 30 μA, ensuring efficient operation.
For connectivity, the module uses a screw terminal connector type. It is compatible with copper wiring, supporting wire gauges from 30 AWG to 14 AWG. The recommended strip length for wire installation is 0.24 inches, with a torque range between 0.22 N · m to 0.25 N · m for securing the connections.
In terms of power consumption, the NI-9485 is highly efficient, consuming only 500 mW in active mode and reducing to 5 mW in sleep mode. It is programmable via LabVIEW Professional Development System for Windows, LabVIEW FPGA Module, and LabVIEW Real-Time Module, offering flexibility in application development. The module weighs 5.1 oz and is designed to operate within a broad temperature range, ensuring reliability and performance in diverse environmental conditions.
